Mollusks are a diverse group of invertebrates that include species such as snails, clams, and octopuses, characterized by a soft body often protected by a hard shell. They play vital roles in ecosystems as grazers, predators, and prey, and have significant economic importance in fisheries and aquaculture.

Mollusks

Invertebrates are animals that lack a vertebral column, making up approximately 97% of all animal species, and include diverse groups such as insects, arachnids, mollusks, and crustaceans. They play crucial roles in ecosystems as pollinators, decomposers, and as part of the food web, highlighting their ecological importance despite their lack of a backbone.

Ecosystems are complex networks of living organisms and their physical environment, interacting as a system through nutrient cycles and energy flows. They can vary greatly in size and complexity, from a small pond to an entire forest, and are crucial for maintaining biodiversity and ecological balance.

Fisheries

Aquaculture, the farming of aquatic organisms such as fish, crustaceans, mollusks, and aquatic plants, is a rapidly growing sector that addresses global food security and sustainability challenges. It involves controlled cultivation techniques to enhance production efficiency and reduce environmental impacts compared to traditional fishing methods.
